Stem cells can be prompted to develop into bone, instead of muscle or cartilage tissue, if they are grown on a substrate etched with nanoscopic patterns – and no added chemicals – researchers have found.
The discovery could lead to longer-lasting artificial implants that are nano-engineered to encourage suitable tissue to develop around them, experts say.
Commentary: Hopefully this advance will lead to improved treatments for bone diseases including osteoporosis and osteoarthritis.
